Subject: tracing: Have HIST_TRIGGERS select TRACING

From: Tom Zanussi <tom.zanussi@linux.intel.com>

commit 7ad8fb61c4abf589596f0a4da34d987471481569 upstream.

The kbuild test robot reported a compile error if HIST_TRIGGERS was
enabled but nothing else that selected TRACING was configured in.

HIST_TRIGGERS should directly select it and not rely on anything else
to do it.
